EBPECIFIC'ATION forming part of Letters Patent No. 390,750, dated October 9, 1888.

Application filed December 19, 1886. Serial No. 222,005.

To all whom it may concern.-

Be it known that I, JAMES H. BUsELL, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Heel-Trimmer, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure l is an axial section of my trimmer in the preferred form. Fig. 2 is a front view of the same. Figs. 3 and 4 are details. Figs. 5 and 6 are views, like Figs. 1 and 2, of a modified form of my trimmer. Figs. 7 to 14, inclusive, are diagrams for illustration.

The main feature of my invention consists in the combination of a rotary cutter with a rand-knife and recessed guard, the blades of the rand-knife moving between blades of the cutter, and the rand-knife and recessed guard yielding with relation to the cutter as the heel varies in height, as more fully set forth hereinbelow.

Minor features of my invention are set forth hereinafter.

In the drawings, A is the main cutter for trimming the edge of the heel.

D is the rand-knife, E the guide for the corner of the top lift, and F the recessed rand guide or guard; for this part F performs a double function-that is, it is a guide to enter and guide by the rand (or the angle between the heel and upper-leather) and also a guard to prevent the heelseat end of cutter A (and the rand-knife D, when used) from injuring the upper-leather of the boot or shoe.

Both the rand-guide F and the rand-knife D are so mounted that they will move sidewise as the-heel varies in heightthat is, the length of cut varies, being shortest near the corners formed by the breast and edge and longest at the rear of the heel; and I am the first, so far I know, to use a rand-knife and heel-edge cutter self-adjusting to these variations in the height of the heel, and also the first to produce a rotary cutter for finishing heel-edges by using the corner of the top lift as a guide, in which the rand-guide is cupped to receive the heel-seat end of the cutter, and the parts are relatively self-adjusting to suit variations in the height of the heel.

It will be obvious that the cutter A and the (No model.)

guide E for the corner of'the top lift must always remain in close contact, in order that the corner of the top lift maybe used as a patternplate; but it will be equally clear that my invention may be embodied ina device-in which the cupped rand-guide F (and its rand-knife D, when used) has no sidewise motion, but the cutter A and top-lift guide E move sidewise away from the cupped randguide F; more over, that both the cupped rand-guide F and the cutter A with its top-lift guide E may have lateral motion; but the best form of my invention is that shown in the drawings, in which the cutter A and its guide E for the corner of the top lift have no lateral motion, and all the lateral mot-ion is given to the cupped randguide F and its rand-knife D.

In the machine shown in Figs. 1 and 20f the drawings, cutter A revolves with shaft B and has no lateral motion on that shalt. The guide E for the corner of the top lift may revolve with shaft B, or be held stationary, as will be well understood by all skilled in the art, but must, of course, always stand close up to the side of cutter A, so that the short wall of the guide E will be substantially flush with the cutting-edges of cutter A. (See Busell patent, No. 308,056, November 18,1884.) The hubf of the recessed rand guide Fis shown as mounted on a sleeve, B, which loosely fits the outer end of shaft B, so that the rand-guide F and the sleeve B" may move laterally until they strike the head of screw B". This sleeve Bf is splined to the shaft B, and therefore re volves with it when the randknife D is used, for the rand-knife'D is made fastto sleeve B by screws f, as it must, of'course,-revolve in order to cut out the rand. The recessed randguide F, I have shown as a cup; but it may of course he a segment. Itis preferable in practice to make it a complete cup when the rand knife D is used with it; but when not so used, as is the ease in some kinds of heels, it may be a small segment, as will be clear to all skilled in the art. The heel'rest G is supported in any suitable way, too well known to require further description.

In Figs. 5 and 6 the cutter A is mounted on shaft B, which is hollowed out to receive a spindle, B, carrying rand-knife D. Spindle B is kept in the opening in shaft B and compelled to rotate with shaft B by means of a pin, b, passing through slot 1) in spindle B. The guide E is mounted on shaft 13 at one end of the cutter, and the guide E, cutter A, and rand-knife D all rotate together, the blades d of the rand-knife moving back and forth between the blades a in cutter A, according to the variations iii the height of the heels. The rand-knife D is clamped against a shoulder on spindle B by means of a sleeve, B, and a screw, B, which passes through the sleeve into the end of the spindle. On sleeve B, between the head of screw 13 and a shoulder on sleeve B", is loosely mounted my recessed rand-guide F, whose hubf" is slightly shorter than sleeve 13, so that the rand-guide does not rotate with the rand-knife when the heel-trimmer is in use, as will be clear to all skilled in the art; but the rand-knife and rand guide yield together to suit variations in the height of the heel, the recessed randguide receiving more or less of the heel-seat end of the cutter as the heel varies in height.

The operation of my trimmer is as follows: The operator places the corner of the top lift in the angle of the guide Il and tips the shoe so that the rand guide, if both are used, enter between the heel and upper. The heel is held against the trimmer and upon the rest G and turned by hand to present the edge properly, and,as the heel varies in height and the rand-guide and rand-knife together yield with relation to the cutter and guide E, the heel is properly trimmed. The rest G aids the workman in supporting the heel under the blows of the blades of the cutter, which revolves with great speed, commonly about six thousand revolutions per minute. The yielding of. the rand-knife to and from the heelrest G is one of the main objects of my invention, and my trimmer is the first, so far as I know, in which this important feature is found.

The diagram, Figs. 7 to 14, illustrate most of the various manners of using my trimmerthat is, in Fig. 7 the trimmer is adapted to take out the rand; but the top lift is not used as a pattern. Fig. 8 is the same as Fig. 7. except that the heel'rest is used. Figs. 11. and 12 are like Figs. 7 and 8, except that no randknife is used. Figs. 9 and 10 are like Figs. 7

and 8, except that the top lift is used as a pattern. Figs. 13 and 14. are like Figs. 9 and 10, except that no rand-knife is used.

In some factories only one of the forms of my trimmer shown in Figs. 7 to 14 is needed, while in others two or more of them are requisite, depending, as will be clear, upon the style and quality of heels made.

I am aware of the following patents: No. 234,869, to Helms, November 30, 1880; No. 330,008, to Gallagher, November 10,1885; No. 209,787, to Adams, November 12, 1878; No. 322, 945, to Manley, July 28, 1885;'No. 282,857, to Dean, August 17, 1883, and disclaim all that is shown in them.

What I claim is-- 1. In combination, rotary cutter A, having blades a, rand-knife D, having blades cl projecting between the blades (4 of cutter A, near the heel-seat end of the cutter, and recessed guard F, covering a portion of the heel'seat end of the main cutter A, guard F, and land knife D, yielding together with relation to cutter A as the height of the heel varies to cause the uncovered edges of the blades a and the position of blades (1 with relation to the heel-seat portion of the cutter A to vary as the height of the heel varies, all arranged and operating substantially as and for the purpose specified.

2. In combination, cutter A, top-lift guide E at the toplift end of cutter A, rand-knife D, with its blades (7. projecting between blades a, near the heelseat end of cutter A, and 1ecessed guard F, the guard F and rand-knife D yielding together with relation to cutter A and toplift guide E, all arranged and operating substantially as and for the purpose specified.

3. In combination, cutter A, top lift guide E at top-lift end of cutter A, rand-knife D, with its blades d projecting between blades a, near the heel-seat end of cutter A, recessed guard F, and heel-rest G, the guard F and rand-knife D yielding together with relation to cutter A and top-lift guide E, all arranged and operating substantially as and for the pur pose specified.
